Yeast is the most important microbial industry for human beings.
Yeast has been industrialized as a microorganism, and it is also
the most industrialized in the world. Compared with no microbial
species, the world's output has reached millions of tons, all of
which are produced by yeast or yeast products. Because the flour
food that people live on every day must be fermented by yeast, and
all kinds of alcoholic beverages that people like must be fermented
by yeast.
The yeast has great contribution to the human diet. The development
of modern biotechnology has expanded the scope of yeast in human
society. More and more advanced chemical materials, such as organic
acids, alcohols and lipids, are produced by yeast. The development
of yeast production technology provides the society with high
quality and convenient transportation yeast products, which is
convenient for people's life, improves the quality of products, and
promotes the wider application of yeast. The demand for yeast in
the market is also increasing.
At present, the main types of yeast available on the market can be
divided into yeast extract and active dry yeast. The yeast extracts
with higher activity and fermentation speed, strong endurance, low
price and other advantages, and fermentation products of good
flavor, fragrance; the main shortcomings of performance is not
stable in activity, storage conditions must be strictly in the
refrigerator or freezer, low temperature storage and storage time
is short, which is not easy the long-distance transportation and
need to be activated before use. Compared with yeast extract,
active dry yeast has more convenient transportation and no longer
need refrigerated vehicle for long-distance transportation. It has
good stability, fermentation power is greater than yeast extract,
and does not need low temperature storage. It can store for 1-2
years at room temperature, and it is not easy to deteriorate.
In this project, molasses was used as raw material, and ammonium
phosphate was used as nitrogen source and phosphorus source. Modern
biotechnology was applied to obtain the desired products after mild
enzymatic hydrolysis, centrifugation, concentration, spray drying
and so on. Natural meat flavor, sour taste and no general yeast
extract. The product is rich in meat derived amino acids and
physiological active peptides, and has been widely applied for its
natural taste enhancement. It can rapidly improve the flavor and
quality of all kinds of salty food, and is the core ingredient of
the new generation of food processing industry.
(1) It has a strong sense of extension and rounded feeling, without the taste of the extract from the ordinary yeast, which is 4 times the flavor effect of the extract of the ordinary yeast.
(2) Rich in nutrition. Protein is decomposed into small molecule peptides and various amino acids, which have dual functions of nutrition and flavoring.
(3) Easy to use. The amount is unrestricted and is used with other products. It has the effect of meat flavor and flavor doubling.
1. Material balance base
The molasses sugar content is 45-55%, impurities less than 3%,
3%-5% protein,fat 4-6%.
The water content of molasses is 35%, fiber 8-12.5%.
2. Molasses consumption and water comsumption:
It will cost 5 tons molasses to produce 1 ton active dry yeast
powder.
It will cost 3 tons molasses to produce 1 ton active wet yeast
paste (fresh yeast).
It will cost 45 tons water to produce 1 ton active dry yeast
powder.
It will cost 27 tons water to produce 1 ton active wet yeast paste.
3. steam comsumption:
It will cost 8 tons steam to produce 1 ton active dry yeast powder,
5 tons steam for 1 ton wet yeast.
Power supply 3000-4000kwh per 1 ton active dry yeast powder,
2000-3000kwh for wet yeast paste.
